APPARATUS FOR BALANCING, RAISING, OR LOWERING CARRIAGE OR OTHER WINDOWS.

SPECIFICATION forming part of Letters Patent No. 792,602, dated June 20, 1905.

Application filed September 27, 1904. Serial No. 226,152.

To all whom it may concern.-

Be it known that we, WILLIAM LIVING- STONE, secretary, and JAMES STEVENSON, engineer, subjects of the King of Great Britain, residing at Belfast, in the county of Antrim, Ireland, have invented certain new and useful Improvements in Apparatus for Balancing, Raising, or Lowering Carriage or other WVindows, (for which application has been made in Great Britain, No. 9,005, dated April 19, 1904,) of which the following is a specification.

This invention has for its object mechanism connected with the windows of carriages, steamers, and the like whereby the window can be raised and lowered with the greatest ease, while it is not possible for the passengers or others to tamper with the mechanism except by dismantling the carriage door or other structures to which the window is fixed.

The invention will now be described with reference to the accompanying drawings, in which the invention is shown as applied to the window in the door of a railway-carriage, Figure 1 being an elevation of such a door, Fig. 2 an enlarged vertical section, Fig. 3 an enlarged sectional plan, and Fig. 4 a detail view of the handle.

In carrying out the invention the windowframe a is attached at two points I) intermediate between the sides of the door or window box 0 to two endless bands or chains (1, between which a balance-weight e of equal weight to the window is fixed. The balanceweight 0 and window a are so attached to the bands (Z that when the lower edge of the window, which is attached to the bands (1, is at the lowest point the balance-weight is at the highest point, and vice versa. The two bands d pass over pulleys or the like f, arranged on a rod or spindle 9 near the bottom of the doorframe or window-box 0, into which the window-frame (L falls. The two bands d also pass over similar pulleys 71 on a spindle or shaft is near the top of the said window-box or solid portion of the door-frame. On this upper shaft or spindle 7c a bevel-wheel Z is arranged, acting on a second bevel-wheel m, located inside the door or window box 0 nearer On this second bevel wheel m or on its spindle n a sprocketwheel 0 is arranged, while a second sprocketwheel p, also on a spindle, is arranged close to the other end of the upper spindle or shaft 75. A sprocket chain or band Q passes round these two sprocket-wheels 0 and p, while a suitable handle 1' is secured to an enlarged link 3 in the chain g. This handle 1" passes through a long slot t in the covering of the door-frame or window-box and is so arranged as to be capable of being fixed in any position along the slot 15. The arrangement found most preferable for this object is shown in detail in Fig. 4. The handle 1" is mounted on a small screwed shaft a, which'engages in the enlarged link 8, hereinbefore referred to. The handle 1' takes overthe screwed part of this small shaft u, so that on being turned it will approach the frame of the door or window box and be clamped against the same. The small shaft u is provided with a guide-piece 1;, adapted to slide along just inside the door or window box frame and over a bar as, so as to give a purchase for the handle 1- when it is desired to lock the same in position, the provision of the bar as having the advantage of preventing people from getting their fingers into the mechanism.

The mode of action is as follows: When the window a is open, nothing need appear to view except perhaps the very top of the window, on which a linger-ledge to may be arranged, and the slot 25 and the handle 1 proj ecting through it, the handle then being at one end, as shown in Fig. 1, and close to the sprocket-wheel 0. Should the occupant of the carriage wish to partially close the window, he slightly unscrews the handle 1' and pushes or pulls the same sidewise and the window-frame at once rises to a proportionate height where it can be clamped in position by screwing up the handle 1. If it is desired to entirely close the window, the handle is pushed right to the opposite end of the slot 1! and then screwed up again. To open the window, the reverse action is gone through.

It will of course be obvious that instead of the two bands d a single band might be used; but this device would not work smoothly and would not be so good from a constructional point of view. It will also be obvious that the arrangement might be adopted equally well for a window descending from a box above, in which case the parts would simply be reversed.

The invention is applicable not merely for windows, but for shutters, panels, strong blinds, and other articles required to be raised or lowered, while a difl'erent device than that shown for clamping the window in position might be used, such as a ratchet or a hinged handle arranged to take over stops along the slot 25.

We declare that what we claim is 1. In a mechanism for raising and lowering windows in which the horizontal movement of the handle causes the vertical movement of the window, a window-box, a slot in said box, a screwed spindle projecting from said slot, and a handle provided with an internal thread adapted to screw on said spindle and so be clamped against said window box.

2. In a mechanism for raising and lowering windows, a window-box to receive the window, a handle capable of horizontal movement, means intermediate the handle and the window whereby the horizontal movement of the handle is converted into a vertical movement of the window, a slotted part, a bar over which the slotted part takes, and a shaft on said. slotted part on which shaft said handle is adapted to screw.

3. In a mechanism for raising and lowering windows, a window-b ox, a handle extend.- ing to the exterior of said window-box, vertical bands secured to the window, means for operating said vertical bands on the horizontal movement of said handle, guiding means for said handle interior ol said box, and

means for clamping said handle in position on turning the same, substantially as de scribed.

4. In a mechanism for raising and lowering windows, a window-box, a handle extending to the exterior of said window-box, a horizontal slot to allow of the movement of said handle, guiding means interior of said box for said handle, screw means intermediate said handle and said guiding means, vertical bands secured to the window, bevelgearing actuated by the horizontal movement of said handle, and means for actuating the said vertical bands by the bevel-gearing, substantially as described.

5.
